let two integers be x and y

A.T.Q

x+y= -3

or, x= -3-y(i)

and xy= -18

or,(-3-y)y= -18[by(i)]

or,- -3y-y²= -18

or,-y²= -18+3

or, -y²= -15

or, y²=15

therefore y=✓15

from (i)

x= -3-✓15

y=√15

Answer:

3 and -6

Step-by-step explanation:

1. First, let's find the factors of -18

  • -1 and 18, or -18 and 1
  • -2 and 9, or -9 and 2
  • -3 and 6, or -6 and 3

2. Next, we have to find which of the factors add up to -3.

  • -1 + 18 = 17
  • -18+1=-17
  • -2+9=7
  • -9+2=-7
  • -3+6=3
  • -6+3=-3

3. Great! Now that we found the factors that result in a product of -18 and a sum of -3, the factors are 3 and -6.

In the xy-plane, the line x + y=k, where k is a constant, is tangent to the graph of y=x^2+3x+1. What is the value of k?
Talja [164]
Slope of tangent line = dy/dx = 2x+3
k is y_intercept of tangent line

2x+3 = -1
x = -2
y = (-2)^2+3(-2)+1 = -1

tangent line passes through point (-2,-1)

k = x+y

k = -2 -1

k = -3

A mother is 1 3/4 times as tall as her son. Her son is 3 feet tall. How tall is the mother?
Kobotan [32]
In order to find the answer to this question, you need to multiply the fractions. But before we do that, we need to turn the mixed fraction into a proper fraction. 1 3/4 would turn into 7/4 because you multiply the denominator by the whole number and add the numerator. So we come out with:

7/4 x 3/1 = 21/4

Can we simplify 21/4? No, we can't. However, we need to turn it back into a mixed fraction. We can do that by actually dividing the numbers. 21 divided by 4 is 5 with a remainder of 1, so we come out with our answer.

The mom is 5 1/4 feet tall :) Hope this helps!
